End of Development

NOTE: Caret is no longer being developed. Connectome Workbench is the successor to Caret, and can do many of the same things, while having better controls and new features. It is available here, and is also open source.

Version 5.65 Current Release (27 January 2012)

Downloading the Caret distribution or source code requires a username and a password that is supplied when you REGISTER for Caret. Registration requires you to provide an email address to which a username and password are sent. The only messages sent to your email address in the future are to inform you about new releases of Caret, nothing else.

The Caret distribution is a ZIP file that contains executables for a single operating system along with supporting files.

The scripts call command line utilities in both the Caret (e.g., caret_command) and Freesurfer (e.g., mri_info and mri_convert) software distributions, so both packages must be installed for it to work. The script was tested using Caret Version 5.65 Current Release (27 January 2012) and Freesurfer 5.1 data.

Download Freesurfer_to_PALS-B12 Pipeline Distribution

The pipeline scripts run on Apple's Mac OS X (requires Intel processor and OS X 10.5 or later) and Linux. The scripts call command line utilities in both the Caret (e.g., caret_command) and Freesurfer (e.g., mri_convert) software distributions, so both packages must be installed for it to work: Caret-Version 5.614 (April 22, 2010 or later) and freesurfer-Linux-centos4_x86_64-stable-pub-v4.0.1 or later (not tested with Freesurfer 5).

The pipeline distribution is a ZIP file that extracts into a PALS_B12.LR directory containing scripts and supporting files. Please read the README.txt file in the extracted PALS_B12.LR subdirectory.

Platform Notes

Microsoft Windows Notes

Problems have been reported with Windows computers using non-English character sets (particularly Asian languages). The typical symptom is an out of memory message, often when opening a spec file. The only solution at this time is to use an English character set.

Linux Platform Notes

Many Linux installations contain buggy graphics card drivers and OpenGL libraries. It appears that updates, and especially operating system updates, cause problems with existing graphics card drivers and OpenGL libraries. You can update your graphics card drivers and OpenGL libraries by downloading them from the manufacturer of the graphics card. If your Linux system contains the program "glxgears" (probably installed in "/usr/bin"), try running it. If glxgears starts but crashes, you definitely need to update the graphics card drivers and OpenGL libraries.

There is also a version of Caret that is available from an Ubuntu distribution. This version of Caret may have problems reading Caret's older binary file formats and produce an image similar to the one above.

Source Code Notes

For those who download the source code to build caret:

We do not provide support for versions of Caret that you compile from source code.

We do not provide assistance of any kind for compiling caret or its required libraries from source code.

Compiling caret source code, and its required libraries, is a difficult task.
